No evidence tube entrapment distresses rodents in typical empathy tests

In the first two experiments an empty tube open at one end was placed in different locations. Male hamsters, tested one at a time, tended to stay close to the tube or in it. During the first minute of the...

The effect of repeated blood harvesting from pregnant mares on haematological variables

Studies have been carried out on the effect of large-volume blood harvesting from horses, but they were performed on nonpregnant horses of various breeds other than Icelandic horses. This study aimed to investigate the effect on the haematological variables indicating...

Life in a fishbowl: Space and environmental enrichment affect behaviour of Betta splendens

The public has expressed growing concern for the well-being of fishes, including popular pet species such as the Siamese fighting fish (Betta splendens). In captivity, male Bettas behave aggressively, often causing injuries and death if housed together. As a result,...

The influence of water nitrate concentration combined with elevated temperature on rainbow trout Oncorhynchus mykiss in an experimental aquaponic setup

Intensive recirculating systems are a fast-developing sector of aquaculture. While several warm-water fish have been reared in aquaponics, almost no data are available for cold-water species. The determination of nitrate toxicity thresholds in recirculating aquaculture is crucial. Different pollutants are...

Development of a novel primate welfare assessment tool for research macaques

Primates are important species for biomedical research and ensuring their good welfare is critical for research translatability and ethical responsibility. Systematic animal welfare assessments can support continuous programme improvements and build institutional awareness of areas requiring more attention. A multi-facility,...

Eugenol as anesthetic for Cnesterodon decemmaculatus (Cyprinodontiformes, Poeciliidae)

Anesthetics are commonly used in fish for surgery and to facilitate capture, handling and transport in aquaculture and experimental procedures. In research, the selection of the anesthetic depends on its properties and on the recovery time. Eugenol has been pointed...

Effects of different tank sizes on laboratory rare minnow (Gobiocypris rarus)-Under the same density

Laboratory fish play an important role in many research fields, and they are also raised and bred in many laboratories around the world. While many studies have suggested suitable feeding densities for various laboratory fish, significant variations exist in the...

Opportunistically using a Chronic Unpredictable Stress study to investigate ‘inactive-but-awake’ behaviour as a potential welfare indicator in laboratory rats

Being awake but motionless, inactive-but-awake (IBA), has been suggested to reflect low arousal negative affect in several species. This preliminary study investigated IBA in rats exposed to Chronic Unpredictable Stress (CUS), opportunistically (to comply with the 3Rs) during biomedical research...

The arterial blood sampling associated with PET imaging studies can lead to post-scan complications in Göttingen minipigs

When disease progression or treatment effects are investigated, pigs are frequently used for imaging studies. We recently showed that prolonged anesthesia with intensive blood sampling and road transportation affect internal organs in non-recovery imaging studies in domestic pigs. In the...
